Movie Oubliette

Dan and Conrad join Bill Pullman on a khaki-clad tour of Haiti in search of a powder that turns people into zombies, in Wes Craven's often overlooked dark fantasy thriller The Serpent and the Rainbow (1988). It has everything you want in a travelog: candlelit processions to a cathedral of waterfalls, exploring a vibrant culture torn by revolution, and getting your scrotum nailed to a chair. Is it an under-appreciated serious work from a director keen to grow beyond his type-casting as a master of horror, or is it a crusty cadaver that should have stayed buried?
